A series of 4-aminomethyl-2, 3, 4, 9-tetrahydrothiopyrano [2, 3-b] indole derivatives was synthesized and evaluated for analgesic activity. Preliminary structure-activity relationship analysis showed that substitution on the benzene portion of the indole ring reduced the analgesic activity, whereas a short-chain Nb-alkyl substituent enhanced the potency, as exemplified by an Nb-methyl substituted analogue. This compound was equipotent to morphine in the acetic acid writhing assay using mice.
合成了一系列4-氨基甲基-2, 3, 4, 9-四氢噻吡喃[2, 3-b]吲哚衍生物,并评估其镇痛活性。初步的结构—活性关系分析表明,吲哚环的苯环部分的取代会降低镇痛活性,而短链的Nb-烷基取代基则增强了效能,以Nb-甲基取代的类似物为例。该化合物在醋酸扭缩实验中与吗啡的效力相当。
